"They were very professional. Every employee new their task and performed it to their best ability. I asked how long it would take to perform job, they said 4 days. They worked through inclement weather which impressed me and at the end of 4 days it was complete. The landscaping they did to finish the outside of project was done and it looked amazing. Inside clean up was done and looked great. This work crew was amazing. Yes I would recommend this company to anyone."

"Straightline did a great job. Cody was in touch and monitoring the progress frequently all three days. I did have one small concern but Cody immediately responded and resolved it. Rain caused a delay but they finished when promised just in time for the next rain/wind storm. It was nice not seeing shingles flying off the house for a change!! I had two previous layers so they had to strip it bare. I have a powerful magnet mounted on wheels. I ran it around the house and found ONE nail in the grass!! That's impressive!!"

"Curt, James, and Junior were all professional, efficient, courteous, and knowledgeable when they came to help me install a new water heater. Being a new homeowner, I was worried having to get a new water heater so soon, but they helped me understand what was happening, worked with me on the cost and breaking down each cost factor, and they helped me understand my options regarding moisture/mold potential. I would 100% recommend them for any plumbing/restoration needs you have!!"

Basement Waterproofing questions, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.
